Step 1

Wash mirror tiles in warm water and dishwashing detergent. Let dry.

Step 2

Place a strip of double-sided tape around the bottom of one cone. Stick silver and blue 1 cm (1/2 inch) square mirror tiles onto the tape in a random order. Place another strip of tape around the cone above the first row of tiles. Stick tiles onto the tape as before. Continue adding tiles until all but about 1 cm (1/2 inch) at the top of the cone is covered with tiles.

Step 3

Apply tape around the top of the cone, as before. Stick 2.5 x 0.5 cm (1 x 1/4 inch) tiles vertically around the top of the tree. Glue a silver ball ornament on top. Repeat the process with the other two Styrofoam cones.
